ABSTRACT
Due to the important roles in ocean mixing, mass transport, and sediment resuspension, mode-2 internal solitary waves (ISWs) have attracted researchers’ interest in the recent years. Synthetic aperture radar, with the capability to image the two-dimensional ocean surface, has become a significant tool for the study of ISWs. This chapter summarizes recent investigations about mode-2 ISWs around the global ocean-based on-remote sensing techniques (especially SAR sensors), in situ measurements as well as numerical models. The signature patterns of mode-2 ISWs on SAR images are introduced. The generation mechanisms of mode-2 ISWs in the South China Sea, the Mascarene Ridge in the Indian Ocean, the Andaman Sea, Mozambique Channel, and so on, are reviewed.
